Comparative standard reference: DIN-53516、ISO-4649、GT/T9867/SATRA TM174、BS-903
Standard Reference Elastomers (SRE): BAM-E001
Comparative standard reference compound No. 1 for abrasion testing according to ISO 4649
Scope and field application
Standard reference compound No. 1 is used for comparative abrasion tests described in the above mentioned standards. It establishes a uniform, steady level of abrasion loss. This level is defined as 200 mg mass loss under definite test conditions (ISO 4649: method A).
